no komi (version 2)
No komi refers to the fact that historically there was no komi to compensate White for Black's right to move first, i.e. an initial advantage of e.g. 5,5 points. In those days White was usually the better player and their goal was to catch up with the weaker player taking Black. That, or the encounter included multiple games where the players would alternate colors (see jubango). Jigo was a possible outcome, i.e. an even score.
